RYRCNT is used for setting/counting in the BCD-coded year section. The count operation is
performed by a carry for each year of the month counter.
The assignable range is from 0000 through 9999 (practically in BCD), otherwise operation errors
occur. Carry out write processing after stopping the count operation through the setting of the
START bit in RCR2.
